Influenza Disease Common and Scientific Name:
This is the Influenza Disease, which is also known as “The Flu”. It can be caused by the viruses Orthomyxoviridae Influenza Virus (A)(B)(C)(D).
Classification:
The classification for Influenza is Virus, Orthomyxoviridae, Orthomyxovirus Influenza (A)(B)(C)(D)
Orthomyxoviruses are usually spherical and are 80-120 nanometers diameter wise. These are usually six to eight segments of linear, single-stranded RNA. Influenza viruses are categorized into types A, B, C, and D according to the variation in nucleoprotein antigen. The difference is that in types A and B are usually the ones that cause new strains. Type C is antigenically stable.

Advanced symptoms include cardiovascular system failure, respiratory system failure, kidney failure, and pneumonia these symptoms are rare and usually only appear in the elderly.
Mode of Transmission and Geographic Location:
Influenza can be contacted due to close contact with infected individuals, influenza actually originated in Spain, but since then it has spread worldwide with the exception of possibly Antarctica.
Treatment:
Some initial treatments are drinking plenty of fluids, rest, pain relievers (optional), antiviral medication such as Tamiflu or Relenza, these medications will allow you to recover a few days faster than average.
There aren’t any long term treatments for Influenza, but there are many long term treatments for its complications such as diuretic medication, getting a tracheostomy, or receiving a kidney
The Influenza virus is a unique respiratory viral disease that can have serious economic and social disruption to society. The virus is airborne transmitted through droplets release by coughing or sneezing from an infected person or by touching infected surfaces. Symptoms range from mild to severe and may even result in death. People with the virus usually experience fever, headache, shivering, muscle pain and cough, which can lead to more severe respiratory illness such as pneumonia. People most susceptible to the flu virus are elderly individuals and young children as well as anyone whose health or immune system has been compromise. The most effective way to counteract the influenza virus is to get the flu vaccine which is available by shots or nasal spray before the flu season as well as practicing safe hygiene. (CDC, 2013)
Current influenza vaccines are about 70% to 90% effective in preventing influenza in healthy adults. Since the vaccines are made of dead fragments of influenza viruses, they cannot cause influenza. The strains of influenza that circulate change every year and therefore, it is necessary to make a new influenza vaccine annually. After vaccination, the body's immune system produces antib... ... middle of paper ... ...
One of the most virulent strains of influenza in history ravaged the world and decimated the populations around the world. Present during World War I, the 1918 strain of pandemic influenza found many opportunities to spread through the war. At the time, science wasn’t advanced enough to study the virus, much less find a cure; medical personnel were helpless when it came to fighting the disease, and so the flu went on to infect millions and kill at a rate 25 times higher than the standard.
The influenza virus is most commonly spread from person to person by coughing or sneezing. The virus can also be spread by touching an object that was recently contaminated. Then accidently touching their mouth or
...influenza pandemic in one way or another; the use of quarantines were extremely prevalent among them. Also, the pandemic is directly responsible for the creation of many health organizations across the globe. The organizations help track and research illnesses across the globe. The CDC (Centers for Disease Control and Prevention) for example, strive to prevent epidemics and pandemics. They also provide a governing body with directives to follow in case an outbreak does occur, and if one shall occur the efforts of organizations across the globe will be crucial for its containment. It is amazing that with modern medicine and proper organization that influenza still manages to make its appearance across the globe annually.
Influenza is a major public health problem which has outbreaks all over the world. Resulting in considerable sickness and death rates. Furthermore, it is a highly infectious airborne disease and is caused by the influenza virus. Influenza is transmitted easily from one person to another person, which has a great impact on society. When a member of society becomes sick, it is more prone to spread to other people.
Influenza is very contagious and spreads rapidly from person to person. Influenza causes worldwide yearly epidemics. According to World Health organization Influenza affects 5-15% world’s population and resulting in 500,000 deaths yearly. Ottenberg stated that, in United States, an average of 200,000 were hospitalized and 36,000 died each year from influenza complications. Influenza is the sixth leading cause of death among US adults and is related to 1 in 20 death in persons older than 65 years. Disease control and prevention estimates indicate that infections like H1N1 which is one of the types of influenza, have resulted in an estimated 42 to 86 million cases and 8520 to 17620 deaths. As I mentioned earlier that infections like influenza are very contagious, they can spread easily from hcw to Patient and back to hcw. The most efficient and effective method of preventing influenza infection is vaccination(The best way to prevent influenza is with annual vaccination).(Sullivan,2010) (Gregory,Tosh &Jacobson, 2005). Motivated by a desire to actively avoid illness Influenza may increase the risk for death in people with existing heart, lung, or circulation disorders. In fact, the higher than average number of winter deaths in people with heart disease may be due only to the occurrence of influenza during those months.Vaccination provides immunity to fight against infection.To increase resistance to harm by modifying the environment to minimize preventable illness (NEED TO CHANGE WORDING)
The influenza pandemic of 1918-1919 killed more people than the Great War, known today as World War I (WWI), at somewhere between twenty and forty million people. (1) Influenza is a virus that appeared in 1918 and caused a pandemic. It made an enormous impact that is still significant to the world today. It has pushed scientists to make advancements in the medicine and vaccination industry that continue to grow each and every day. Influenza may be a horrible thing, but without it we wouldn’t be where we are today.
After careful observation by medical specialists around the country, it is established that the present form of influenza is no different from any other form of influenza in English history. Influenza in the epidemic form has visited England previously in 1709, 1732 as well as in 1890.1

The swine influenza or swine flu is a respiratory disease in pigs that is caused by the type A influenza viruses. These viruses are referred to as swine flu viruses but scientifically the main virus is called the swine triple reassortant (tr) H1N1 influenza virus. When the viruses infect humans they are called variant viruses. This infection has been caused in humans mainly by the H1N1v virus in the United States. The H1N1 virus originates in animals due to improper conditions and the food they ingest. The virus stays in latency form, thus harmless to the respective animal. The longer the animals survive the more likely the virus is to develop and strengthen making it immune to vaccines. The virus reproduced through the lytic cycle. The virus injects its own nucleic acids into a host cell and then they form a circle in the center of the cell. Rather than copying its own nucleic acids, the cell will copy the viral acids. The copies of viral acids then organize themselves as viruses inside of the cell. The membrane will eventually split leaving the viruses free to infect other cells.
The Flu was first founded in Seattle September, 1918. The avian flu can also be known as the “Bird Flu”. The bird flu is being passed around by migratory birds. It can be transmitted from birds to mammals and in some limited circumstances to humans. The flu will also be known as the H5N1 virus. The H5N1 virus has raised concerns about a potential human pandemic because its virulent (deadly; extremely dangerous) and it can evolve like other influenza viruses. As many other viruses and illnesses the flu can be a lot more deadlier. When you get the flu the lungs are severely harmed from infected cells called macrophages and T-cells. The virus can spread way beyond the lungs but generally do not. Many people catch the flu and think they have the common cold because of some of the same symptoms. But actually the flu can be more dangerous if you don’t treat it immediately.
